Prosecutors say Blair helped 21-year-old John T. Booker in his plot to plant a 1,000-pound bomb at the Fort Riley military base to aid the Islamic State group. Blair admitted in court that he loaned Booker $100 to secure a storage space for the explosives and failed to inform law enforcement of the plot.
